Description
Technical Field
The invention relates to a disinfectant, in particular to a corrosion inhibition disinfectant for the industrial field.
Background
With the development of social economy, people frequently go out of public places, and public transportation handrails, public facilities, computer keyboards, mobile phones and the like become media for spreading viruses and bacteria. According to statistics, the number of infectious diseases caused by the contact of virus and bacteria in daily life of people is up to 2000 to ten thousand every year. The disinfection of daily hand, household environment, daily necessities and public environment disinfection is more and more emphasized. Safe, healthy, environment-friendly and efficient disinfection products have wide markets. The disinfectant used in common use is mainly 9 types according to component classification: chlorine-containing disinfectants, peroxide disinfectants, aldehyde disinfectants, alcohol disinfectants, iodine-containing disinfectants, phenol disinfectants, ethylene oxide, biguanide disinfectants and quaternary ammonium salt disinfectants. The 84 disinfectant is a chlorine-containing disinfectant, the main component of which is sodium hypochlorite, and has the characteristics of strong capability of killing bacteria and viruses, wide sterilization range, quick action and no pollution to the environment. The production process is relatively simple, the manufacturing cost is low, and the method is widely applied to the fields of medical treatment and health, household cleaning and the like.
At present, the 84 disinfectant is mainly used in household cleaning, office environment and public places and cannot be widely applied to the industrial field, and the reason is that the 84 disinfectant is a chlorine disinfectant, wherein the chlorine ions have small volume and high activity and strong capability of penetrating through metal surfaces, and the breakage points of the chlorine ions become active etching holes (serving as anodes) and surrounding passive surfaces (serving as cathodes) to form a short-circuit battery. The formation of the electrochemical corrosion is corrosive to metals of different materials such as carbon steel, stainless steel, aluminum, copper and the like, so that metal parts of machine tools, metal equipment and disinfection equipment, such as spray irrigation nozzles, are rusted.
Therefore, the search for a disinfectant solution which does not corrode metals is a technical problem to be solved in the field.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a corrosion inhibition disinfectant for the industrial field.
In order to achieve the purpose, the invention adopts the technical scheme that: a corrosion inhibition disinfectant liquid used in the industrial field comprises the following components: the disinfectant comprises a sodium hypochlorite disinfectant, an antirust agent, an alkali value providing agent and a nonferrous metal corrosion inhibitor, wherein the sodium hypochlorite disinfectant selected in the invention is 84 disinfectant.
Preferably, the corrosion inhibition disinfectant comprises the following components in parts by weight: 60-98 parts of sodium hypochlorite disinfectant, 0.1-2 parts of antirust agent, 0.5-6 parts of base number provider and 0.1-5 parts of non-ferrous metal corrosion inhibitor.
Preferably, the corrosion inhibition disinfectant comprises the following components in parts by weight: 70-98 parts of sodium hypochlorite disinfectant, 0.3-1.5 parts of antirust agent, 0.8-4 parts of base number provider and 0.1-3 parts of non-ferrous metal corrosion inhibitor.
Preferably, the corrosion inhibition disinfectant comprises the following components in parts by weight: 95-98 parts of sodium hypochlorite disinfectant, 0.5-1.0 part of antirust agent, 1-3 parts of base number provider and 0.3-1 part of non-ferrous metal corrosion inhibitor.
Preferably, the antirust agent is any one of sodium nitrite and sodium molybdate or the combination thereof. The sodium nitrite and/or the sodium molybdate are selected because the sodium nitrite belongs to an anode type corrosion inhibitor and is also an oxide film type corrosion inhibitor, so that a passive extremely thin compact oxide film can be formed on the surface of metal, the ionization of the metal is hindered, the corrosion electrochemical anode reaction is inhibited, and the corrosion of the metal is slowed down. The sodium molybdate corrosion inhibition mechanism is similar to that of sodium nitrite, and the corrosion of chlorine-containing disinfectant on metal is slowed down by providing an oxidation protection film.
Preferably, the base number provider is: one or more of monoethanolamine, diethanolamine, triethanolamine, potassium hydroxide and sodium hydroxide. According to the invention, monoethanolamine, diethanolamine, triethanolamine, potassium hydroxide or/and sodium hydroxide are selected, because ethanolamine, diethanolamine, triethanolamine, potassium hydroxide and sodium hydroxide are added into the disinfectant, the alkalinity of the solution can be effectively increased, the pH value of the solution is improved, but the pH value of the solution is not too high, repeated adjustment of the invention finds that when the pH value of the solution is more than 10, alkali reacts with steel metal to generate a barrier layer of ferrous hydroxide, the metal surface is separated from the liquid, and the corrosion rate is effectively reduced.
Preferably, the nonferrous metal corrosion inhibitor is benzotriazole or/and phosphate ester. The benzotriazole and/or phosphate are selected because the benzotriazole and copper can form a chain-shaped semi-permanent polymerization complex film, has good adhesion and has good protection effect on copper alloy. The phosphate can obviously reduce the metal corrosion speed, and is mainly used as a corrosion inhibitor for non-ferrous metal alloys such as magnesium, aluminum and the like.
The invention has the beneficial effects that: the invention effectively improves the disinfection and corrosion inhibition effect of the disinfectant by the matching use of the disinfectant, the corrosion inhibitor, the base number providing agent and the antirust agent, and can effectively improve the synergistic effect of the components by the research on the components and the matching effect of different corrosion inhibitors, disinfectants and antirust agents, and the disinfection and corrosion inhibition effect is good. The disinfectant is safe and nontoxic, and products treated by the disinfectant meet the high-efficiency disinfection standard, can effectively delay or inhibit the corrosion of metal products, and has the characteristics of safety, no toxicity, and the like.
